FATAL: terminating connection due to administrator command

please see the following snippet

Feb 27, 2006 6:23:51
.DMException: java.sql.SQLException: FATAL: terminating connection due to administrator command

this error message is in one of the log files, and because of the above error the desired job does not get executed

i tried to see the postgreslog.

the log message around that time are as follows:
<2006-02-27 18:23:52 CST%>LOG: connection received: host=localhost.localdomain port=33256

please note the lines in bold, is it because of this EOF on client connection that ... the DMException is coming.


will be glad if any hints could be provided.

this is Postgres 8.0.0

thanks,
